Usage

Step 1: Install plugin:

npm install --save-dev postcss @dialpad/postcss-responsive-variations

Step 2: Check your project for existing PostCSS config: postcss.config.js in the project root, "postcss" section in package.json or postcss in bundle config.

If you do not use PostCSS, add it according to the official docs and set this plugin in settings.

Step 3: Add the plugin to the plugins list:

module.exports = {
  plugins: [
+   require('postcss-responsive-variations'),
    require('autoprefixer')
  ]
}

Step 4: Create the responsive breakpoints and the classes you need and pass them to the plugin argument. Note: if you don't pass the breakpoints, the plugin will use the default ones, which are the ones shown in this example.

+const breakpoints = [
+  { prefix: 'sm\\:', mediaQuery: '(min-width: 480px)' },
+  { prefix: 'md\\:', mediaQuery: '(min-width: 640px)' },
+  { prefix: 'lg\\:', mediaQuery: '(min-width: 980px)' },
+  { prefix: 'xl\\:', mediaQuery: '(min-width: 1264px)' },
+];

+const classes = [
+ '.foo',
+ /\.bar-*/
+];

module.exports = {
  plugins: [
+   require('postcss-responsive-variations')({breakpoints, classes}),
    require('autoprefixer')
  ]
}
